[0030] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0031] like Figure 1-3 As shown, an embodiment of the utility model discloses a cervical treatment drug delivery device, including a cylinder 1 with an opening at the bottom, a push block 2 is slidably connected to the cylinder 1, a push rod 3 is fixedly connected to the push block 2, and the push rod 3 extends downward from the cylinder 1, the top end of the cylinder 1 is hemispherical, the top end of the push block 2 is hemispherical, the top surface of the push block 2 can abut against the top inner wall of the cylinder 1, the top end of the cylinder 1 is fixedly connected to a conical cylinder 4, the conical cylinder 4 is connected to the internal space of the cylinder 1, and the conical cylinder 4 is made of rubber material.

[0032] Specifically, in the initial state, the push block 2 abuts against the top inner wall of the cylinder 1; the conical cylinder 4 is connected to the device for storing the medicine, and then the push rod 3 is pulled, so that the push rod 3 drives the push block 2 to move in the direction away from the hemispherical end of the cylinder 1, thereby sucking the medicine into the cylinder 1; then the cylinder 1 is inserted into the patient's body, and when the conical cylinder 4 is inserted into the patient's cervical opening, the push rod 3 is pushed, so that the push rod 3 drives the push block 2 to move in the direction close to the hemispherical end of the cylinder 1, thereby pushing the medicine into the patient's body through the conical cylinder 4.

[0033] Through the setting of the cylinder 1, the medicine can be stored in the cylinder 1 to avoid the loss of the medicine during the insertion of the cylinder 1 into the patient's vagina. At the same time, through the setting of the conical cylinder 4, the cylinder 1 can drive the conical cylinder 4 to insert into the patient's cervical opening, which is convenient for the entry of the medicine. At the same time, the conical cylinder 4 is made of rubber material to avoid discomfort to the patient when the conical cylinder 4 is inserted into the patient's cervical opening. Moreover, through the setting of the push block 2 and the push rod 3, the medicine can be pushed into the patient's cervical opening to ensure the therapeutic effect of the medicine.

[0034] like Figure 1 , 2 As shown in , 3, 4, and 5, an auxiliary mechanism 5 is provided on the cylinder 1, and the auxiliary mechanism 5 includes a blocking member 51, and the blocking member 51 includes a baffle 511 slidably mounted on the cylinder 1, and a mounting ring 512 is fixedly connected to the baffle 511, and the mounting ring 512 is mounted on the cylinder 1. A through hole 513 is opened on the vertical side of the mounting ring 512, and a limiting rod 514 is slidably connected in the through hole 513. The end of the limiting rod 514 away from the cylinder 1 is fixedly connected with a fixing plate 515, and a first spring 516 is connected between the fixing plate 515 and the mounting ring 512. Ten limiting holes 517 are opened on the cylinder 1 at equal intervals along its axial direction, and the limiting rod 514 can be inserted into the limiting hole 517.

[0035] Specifically, in the initial state, the limiting rod 514 abuts against the outer circumferential surface of the barrel 1, and the first spring 516 is in a compressed state; when in use, during the process of the barrel 1 being inserted into the patient's body, the baffle 511 contacts the patient's body, and the baffle 511 is blocked by the patient's body, so that the baffle 511 moves relative to the barrel 1 in a direction away from the hemispherical end of the barrel 1. When the conical barrel 4 is inserted into the cervical opening, the movement of the barrel 1 is stopped, and the baffle 511 is rotated at the same time, so that the baffle 511 drives the mounting ring 512 to rotate, and the mounting ring 512 drives the limiting rod 514 to rotate until it is in the same straight line with the ten limiting holes 517 and stops rotating. The limiting rod 514 is inserted into the limiting hole 517 at the corresponding position under the elastic force of the first spring 516, so that the baffle 511 is relatively fixed to the barrel 1, and then the push rod 3 is pushed to push the drug into the patient's body.

[0036] By setting the blocking member 51, after the conical cylinder 4 is inserted into the patient's cervical opening, the baffle 511 is relatively fixed to the cylinder body 1, so that when the push rod 3 pushes the medicine into the patient's cervical canal, the external force on the cervical opening is small, and the main thrust is borne by the body part in contact with the baffle 511, avoiding the patient's cervical opening feeling discomfort during the process of pushing the medicine, and facilitating the operation of the operator; and through the setting of multiple limiting holes 517, it can be used for patients of different body shapes, thereby improving the applicability of the drug delivery device.

[0037] like Figure 3 , 4As shown in Figures 5 and 9, the auxiliary mechanism 5 also includes a lubricating member 52, which includes a cylindrical storage cavity 521 provided in the cylinder 1, a push ring 522 being slidably connected in the storage cavity 521, four hollow tubes 523 being evenly and fixedly connected to the bottom wall of the storage cavity 521 along the circumferential direction, the push ring 522 being slidably sleeved on the four hollow tubes 523, and two liquid inlet holes being provided at the bottom of each of the hollow tubes 523, the liquid inlet holes connecting the hollow tube 523 with the liquid inlet holes. The storage chamber 521 is connected, and lubricating oil is stored between the push ring 522 and the bottom wall of the storage chamber 521. The top of the storage chamber 521 is connected to eight oil outlet holes 524, and the oil outlet holes 524 are connected to the external space. The oil outlet holes 524 are located at the top of the cylinder 1. A limiting ring 525 is fixedly connected to the inner wall of the storage chamber 521, and the limiting ring 525 is located on the upper side of the push ring 522. The hollow tube 523 passes through the limiting ring 525.

[0038] Specifically, during use, when the cylinder 1 moves into the patient's body, the push ring 522 moves in the direction away from the top hemispherical end of the cylinder 1, and the push ring 522 squeezes the lubricating oil in the storage chamber 521 into the hollow tube 523 through the liquid inlet hole at the bottom of the hollow tube 523, and then the lubricating oil enters the patient's body through the oil outlet hole 524.

[0039] By setting the lubricating member 52, when the barrel 1 is inserted into the patient's body, lubricating oil can be discharged through the oil outlet hole 524, which facilitates the barrel 1 to enter the patient's vagina and facilitates the drug administration.

[0040] Furthermore, the push ring 522 and the baffle 511 are magnetically attracted to each other.

[0041] Specifically, when the baffle 511 moves, the baffle 511 drives the push ring 522 to move through the magnetic force, thereby pushing out the lubricating oil in the storage chamber 521 to facilitate the entry of the cylinder 1.

[0042] like Figure 7 , 8 As shown, the auxiliary mechanism 5 also includes a discharge piece 53 arranged in the push block 2, and the discharge piece 53 includes a mounting cavity 531 opened in the push block 2, and the push rod 3 extends into the mounting cavity 531. A fixed plate 532 is fixedly connected to the push rod 3, and the fixed plate 532 is slidably connected to the inner wall of the mounting cavity 531. An air hole 533 is opened on the top wall of the mounting cavity 531, and a one-way valve is arranged in the air hole 533.

[0043] Furthermore, the gas can only enter the cylinder 1 from the installation cavity 531 through the one-way valve.

[0044] like Figure 7 , 8As shown in Figure 9, the discharge member 53 also includes two insertion holes 534 symmetrically opened on the push rod 3, and two rod sleeves 535 are symmetrically fixedly connected to the inner wall of the mounting cavity 531, and an insertion rod 536 is slidably connected in each of the rod sleeves 535, and the top surface of the insertion rod 536 is an inclined surface, and a second spring 537 is connected between the insertion rod 536 and the rod sleeve 535. Two sliding grooves are symmetrically arranged on the push block 2 and the fixed plate 532, and an abutment plate 538 is slidably connected in the sliding groove, and the abutment plate 538 can abut against the top surface of the insertion rod 536, and two abutment blocks 539 are symmetrically fixedly connected to the inner wall of the top end of the cylinder 1, and the abutment blocks 539 can be inserted into the sliding groove and abut against the abutment plate 538.

[0045] Specifically, during use, when the push block 2 moves to the top of the cylinder 1, the abutment block 539 is inserted into the slide groove, and the abutment block 539 abuts against the abutment plate 538. As the push block 2 continues to move upward, the abutment block 539 drives the abutment plate 538 to continue to move downward, and the abutment plate 538 abuts against the top surface of the insertion rod 536, so that the insertion rod 536 moves out of the insertion hole 534 and compresses the second spring 537. At the same time, the top surface of the push block 2 abuts against the top inner wall of the cylinder 1, and then continues to push the push rod 3 upward. The push rod 3 drives the push block 2 to move, and the push block 2 drives the fixed plate 532 to move upward, and the gas in the installation cavity 531 is discharged into the conical cylinder 4 through the air hole 533, and the residual medicine in the conical cylinder 4 is blown into the patient's cervix.

[0046] By setting the discharge piece 53, when the push block 2 pushes the medicine into the patient's cervix, the gas discharged from the installation cavity 531 can blow the remaining medicine in the conical tube 4 into the patient's cervix, thereby avoiding the residue of medicine in the applicator and further improving the treatment effect.

[0047] like Figure 7 , 8 As shown, a through slot is provided in the push rod 3 , the through slot is communicated with the mounting cavity 531 , the through slot extends downward and passes through the push rod 3 , and a closing cover is threadedly connected to the lower opening of the through slot.

[0048] Specifically, during use, after the medicine in the barrel 1 is completely pushed into the patient's cervix, the sealing cover is opened, and other medicines that need treatment are delivered to the patient's cervical canal through the through groove and the conical barrel, thereby improving the applicability of the device.
